Optimus Prime - The Altruistic leader of the Autobots who comes to Earth to destroy the All Spark in order to end the war. He transforms into a Blue Peterbilt 379 Semi Truck with Red Flame decals which is a modernized version of his G1 mode. His weapons include an energy rifle that unveils from his back, two retractable energon blades that extend from both forearms, Ion cannons on both of his arms, as well as two retractable energon hooks on both of his forearms..Optimus Prime arrives on Earth at the same time as Ironhide, Jazz and Ratchet as a protoform, landing in a field. He scans the new alternate mode of a semi-truck and quickly joins up with Bumblebee and his human companions and tells them of Megatron and his Decepticons. Later on, While evacuating the All Spark from Hoover Dam, Optimus Prime attempts to thwart the Decepticon Bonecrusher's pursuit. After a short battle, Prime beheads Bonecrusher with his retractable blade. Although Prime fights Megatron in a final battle, Sam kills Megatron ramming the All Spark into his chest. Prime, who had planned to destroy the All Spark by placing it into his own chest, is immensely grateful to Sam for saving him. Afterwards, Optimus then takes the remaining fragment of the All Spark. Despite all that has happened, Prime deeply regrets Megatron's death, evidenced by his parting words: "You left me no choice, brother". The film ends with Optimus sending out a deep-space signal, inviting other Autobots to join them on Earth. Screen shot of Optimus as a protoform Here. Concept art of Optimus Here.
Bumblebee - The youngest Autobot that befriends Sam that turns into a 1976 Chevrolet Camaro as a disguise for Sam to buy him from Bobby Bolivia. They eventually purchase Bumblebee, due in no small part to Bumblebee damaging every other car at the dealership to ensure his purchase. Later, Bumblebee drives away from Sam's home to summon the Autobots. Sam witnesses Bumblebee transforming into robot mode at a junk yard where he sends out a signal for his fellow Autobots. Bumblebee battles Barricade and defeats him in order to protect Sam and Mikaela. Later he upgrades as a Fifth Generation Chevrolet Camaro after Mikaela criticizes the poor condition of Bumblebee's vehicle mode. It is revealed later on that his vocal processors were damaged and has to communicate by radio. He can transform his right arm into a plasma cannon and has missile launchers in his shoulders. Bumblebee survives the massive battle at the film's climax, although he loses the use of his legs after helping Ironhide deflect missiles from Starscream. With Mikaela's aid, he is able to rejoin the battle supported by a tow truck and destroys Brawl. After the battle, Bumblebee is fully repaired and asks to stay with Sam and is granted permission from both Sam and Optimus Prime. He is later seen alongside Ironhide, Ratchet, and Optimus watching the sunset while Sam and Mikaela recline on his hood at the end of the movie. Both of the cars he was seen as are original to the movie. Concept art of Bumblebee Here.
Jazz - The Autobot lieutenant who develops a fondness for urban culture. His vehicle form is original to the movie modified hardtop Pontiac Solstice GXP. He is described as a happy-go-lucky Autobot. Good-natured and always able to take things in stride, he provides a decent contrast to the more serious demeanor of Ironhide or Prime himself. Jazz's weapons include a shield and a shield-mounted machine gun. He also possesses a type of electro-magnet in his right arm, which he uses to disarm humans of their guns without causing them injury, curiously leaving jewellery and electronics unaffected. One weapon considered for Jazz was a plasma cannon that combined with his shield, shown in concept art by Hasbro at BotCon 2007. Arriving on Earth at the same time as Optimus Prime, Ironhide and Ratchet, Jazz's protoform lands in Dodger Stadium then re-appears near the Casa De Cadillac car dealership (Sherman Oaks, California). Jazz jumps off the roof of the car shop and quickly scans a modified Pontiac Solstice before meeting up with the other Autobots at Bumblebee's location. In the final battle, when Bumblebee is unable to fight, Jazz provides cover despite being outnumbered three to one. He fights Brawl alongside Ironhide and Ratchet, and then takes on the Decepticon leader, Megatron. He orders Ironhide and Ratchet to fall back, deciding to stand his ground in order to protect the humans running away. Despite his efforts trying to injure Megatron, he is carried atop a building and torn in half by him. Despite Ironhide and Ratchet's best efforts, Jazz does not survive. After Megatron's death by Sam, Prime and the remaining Autobots mourn for Jazz. Concept art of Jazz Here. He is the only Autobot killed in the movie.
Ironhide - The Autobots trigger happy weapon specialist and Optimus's friend that turns into a GMC Topkick Pickup Truck which is original to the movie. His weapons include an energy rocket launcher on his left arm, a plasma rocket launcher on his right arm, with a super gatling gun connected around the outside of the right forearm plasma rocket launcher. Arriving on Earth at the same time as Optimus Prime, (in a pool, to which a young girl asks him if he's the tooth fairy) Jazz and Ratchet. Ironhide quickly sneaks away to a driveway, scans a family's GMC Topkick pickup truck and reconfigures his alternate mode to a new camouflaged form before meeting up with the other Autobots at Bumblebee's location. Upon meeting Sam, Ironhide displays an eagerness to show off his cannons, and made a classic Clint Eastwood impression to show it by saying "You feeling lucky, punk?". At one point, he becomes so frustrated with Sam's parents that he asks Optimus if he can "take them out". He then gets a stern scolding from Optimus, who is frustrated at Ironhide's overuse of cannons. He also ask Sam's permission of exterminating his dog after urinating on his foot as he believes it is a rodent. He is also shown to be slightly contemptuous towards the humans; he questions Prime as to why they should protect the human race, describing them as "primitive" and "violent", only to be reminded that the Autobots were not so different from them once. Ironhide is, despite being easily the bulkiest of the Autobots, a tough warrior endowed with surprising agility, shown in the final battle when he transforms, flips forward, and dodges Brawl's missiles while doing a helix twist at the same time. He was also able to maneuver through the city, and flip over a nearby human without injuring her, rocket jumping over her right after transforming. Ironhide plays a large role in the final battle: when Bumblebee is unable to fight, he provides cover despite being outnumbered three to one. He battles Brawl alongside Jazz and Ratchet in the movie, and engages in a battle with Starscream, with the aid of Ratchet. However, damage sustained in the brief brawl with Starscream leaves both him and Ratchet unable to further protect Sam. After the battle is over, Ironhide brings the remains of his destroyed autobot brother Jazz to Optimus Prime. Ironhide then gives Captain William Lennox a ride home, and is seen alongside Ratchet, Bumblebee, and Optimus watching the sunset or watching Sam kiss Mikaela at the end of the film. Concept art of Ironhide Here.
Ratchet - The Autobot Medic that transforms into a Search and Rescue Hummer H2. His weapons include a Cybertronian rotary saw that emerges from his left arm, and can transform his right and left arm into a medigun. Ratchet also has an assortment of other tools at his disposal, he uses a red laser to scan and try to calibrate Bumblebee's voicebox as they are introduced to Sam Witwicky and Mikaela Banes. He has an enhanced sense of smell. Arriving on Earth at the same time as Optimus Prime, Jazz and Ironhide, Ratchet's protoform crash-lands outside a local diner. Ratchet quickly scans a yellow emergency Hummer H2 and reconfigures his protoform to a new camouflaged form before meeting up with the other Autobots at Bumblebee's location. In the Autobots introductions, Ratchet unintentionally embarrasses Sam in front of Mikaela, as he does not fully understand human social rules yet, commenting "The boy's pheromone levels suggest he wants to mate with the female" by using his enhanced senses. Ratchet also accidentally gets entangled in power lines, sending him spasming to the ground and causing a blackout in the neighborhood. Ratchet also appears to be a very wise Autobot in the film. After Bumblebee's capture, when the Autobots are discussing about the location of the Allspark and their war with the Decepticons for acquiring it first, Optimus states that he intends to unite the Cube with his spark. Ratchet warns him that the Cube's raw power would destroy them both. Moreover, he also tells the Autobots - "I sense the Decepticons are getting ready to mobilize". Ratchet plays a large role in the final battle, where he, Jazz and Ironhide first battle Brawl. Later, he and Ironhide provide cover for Sam against Blackout and Brawl as the latter tries to escape with the Allspark and also engage in a battle with Starscream, who disables both of the Autobots , causing Sam to reach his destination building alone. Ratchet's injuries at the hands of Starscream keep him from getting to Jazz in time before the small Autobot is torn in half by Megatron. Concept art of Ratchet Here. Ratchet was originlly meant to look like this click Here but the producers wanted something else. Hasbro did not mind if the character was either an ambulance or a fire apparatus.
NOTE: Optimus, Jazz, Ironhide and Ratchet arrived on earth as protoforms using a Cybertronian Meteorite. Also Five Dead Autobots are shown in Optimus Prime's flashback to Sam and`Mikaela, they were killed by Megatron.
Megatron - The leader of the Decepticons and primary Antagonist who transforms into a Alien/Cybertronian jet, a version that appears to be entirely unique for the character. He can transform his right hand into a gun, combine both of his arms to form his iconic fusion cannon, and can transform his right arm into a steel flail..Several years after being discovered by Captain Archibald Witwicky, Megatron's frozen body is transported from the Arctic Circle to Hoover Dam to be guarded by Sector 7, a secret government organization that studies extraterrestrial activities. Agent Seymour Simmons explains that the Earth's magnetic field may have interfered with Megatron's telemetry, causing him to crash during the Ice Age. He also explains that his technology was reverse-engineered, producing the world's modern technology. Megatron's location, as well as the All Spark's, is located by a group of Decepticons led by Starscream. After sneaking into Hoover Dam Frenzy thaws out Megatron, who escapes outside and learns from Starscream that the humans and the Autobots have taken the All Spark. Megatron pursues the Autobots and their allies to Mission City, where he quickly disposes of Jazz before battling Optimus Prime. He defeats Optimus and then pursues Sam Witwicky up a condemned building, attempting to taunt and threaten the human into giving him the All Spark. Sam declines, prompting Megatron to knock the boy off the roof of the building with his flail. Optimus saves Sam and battles Megatron again. During the battle, Megatron attempts to seize the Allspark once again, only to have it shoved into his exposed spark chamber by Sam, killing him. Megatron's body is then dumped in the Laurentian Abyss with the other deceased Decepticons. Concept art of Megatron Here.
Starscream - The Decepticon Air Commander & Megatron's second-in-command. Despite being a popular character, his role is limited because of the film's running time. His Alt Form is a F-22 Raptor Fighter Jet, a modernized version of his G1 mode, which is the successor to his original form, the F-15 Eagle. This keeps the character's role as the powerful and technologically advanced air commander. His arms store heavy weaponry, with a missile launcher carrying six missiles in both arms, a saw in his right arm, and a high caliber machine gun. He also has the ability to leap great heights into the air and take flight using the jet's powerful main engines on his back. Starscream rallies the other Decepticons to battle when Frenzy alerts them to the All Spark's location. He destroys the electrical substation that powers Sector 7's base, allowing Megatron to come out of his deep freeze. Upon being reunited with Megatron, however, he is scolded by his leader for letting the All Spark escape in a manner reminiscent of his G1 counterpart: "You've failed me yet again, Starscream". In the final battle between the Autobots and Decepticons, he is the first Decepticon to arrive on the scene thanks to his flight capability, which he also uses to ambush the Autobots when their human allies mistake him for a friendly Air Force pilot. He aids Brawl and Megatron by firing missiles in his Raptor form at Bumblebee and Ironhide, destroying the former's legs and injuring the latter. Later, he stops Sam Witwicky from fleeing by land with the All Spark, easily disabling both Ratchet and Ironhide in the process; however, he does not take the All Spark with him. When Sam is about to hand off the All Spark to a Black Hawk crewman, Starscream shoots down the helicopter. Later, when a full airstrike has been called in on Megatron and Blackout, Starscream conceals himself among the attacking jets in order to ambush them. He destroys three of the jets, but retreats from the battle after the F-22 pilots regroup and engage him, allowing the jets to complete their mission. An interlude during the end credits shows Starscream leaving Earth's atmosphere. He can be heard speaking, though his words are not clear nor subtitled. Concept art of Starscream Here.
Blackout - A MH-53 Pave Low Helicopter, from "Transformers: Energon". Blackout is the first active Decepticon (and first Transformer) to be seen. He is armed with 2 arm-mounted Gatling cannon M134, 2 energy cannons and has the ability to disrupt electronic devices via EMP blasts. He is also able to detach and wield his tail rotor blades as a close-combat weapon. Early in the film, he, along with his minion Scorponok, attacks the SOCCENT Forward Operations Centre in Qatar, disguised as a MH-53M Pave Low IV helicopter, tail number 4500 X, that was apparently shot down over Afghanistan three months earlier. Blackout is escorted to the base by two F-22 jet fighters, where he transforms and single-handedly obliterates the base. He attempts to hack into the base's system to download data on the location of the Allspark and Megatron, only to have the hardline to the system cut by Colonel Sharp. He then deploys Scorponok, sending him after a fleeing Captain William Lennox and his team. Later, Blackout is seen rallying with the other Decepticons to Starscream's call, after Frenzy discovers the Allspark in the Hoover Dam. Arriving in Mission City during the final battle, Blackout attacks Sam, who is saved by the timely intervention of Ironhide. Later he attempts to kill Sam with his rotor weapon. Towards the end of the battle he attempts to ambush Optimus Prime from behind while he is preoccupied fighting Megatron; however, he is attacked by Captain Lennox and his team, the former racing underneath him on a motorcycle and firing at him with a sabot round, along with human pilots in F-22s firing a barrage of missiles from the air, eventually killing him. (The events of "Starscream's Militia" and Alliance issue #2 occur next.) His corpse is disposed of in the Laurentian Abyss, along with Megatron and the other fallen Decepticons. Concept art of Blackout Here.
Frenzy - A small and vicious spy who transforms into a GPX BCDW9815CNP boombox, and later into a mobile phone (both of which are original to the movie). His weapons include a small automatic weapon on each hand and CD-like shurikens that fire out of his chest. His character is manic (living up to his name), sometimes comedic, and he is the only Decepticon with blue colored optics, rather than the usual red. Frenzy first appears when he infiltrates Air Force One to hack into the U.S. military's mainframe to find out Megatron's location. The military officials disrupt the downloads and send three secret service agents after the infiltrator, but Frenzy manages to kill them and escape. He then aids Barricade in locating Sam Witwicky. When let loose on Sam and Mikaela Banes, Frenzy attacks Sam but is decapitated by Mikaela using a reciprocating saw (a circular saw in the comic adaptation). He survives the injury and leaving his inert body behind, his head sprouts spider-like legs for movement, reformats into Mikaela's mobile phone and hides in her bag. Later, he infiltrates the Hoover Dam and uses the power of the All Spark to regenerate his lost body. In the original script as well as the comic adaptation, he reattaches his original body, which is brought to him by the other Decepticons. He then proceeds to shut down the cooling systems, resulting in Megatron's reawakening, and alerts the Decepticons to the All Spark's presence. While attacking a group of humans in the control rooms, Frenzy accidentally kills himself when one of his own shurikens goes full circle and slices his head in two. He stumbles and with the words "oh shi!" he falls to the floor presumebly dead. Concept art of Frenzy Here.
Barricade - A Saleen-Modified Ford Mustang Police Cruiser whom Frenzy guides to Sam. The character was inspired by the G1 Autobot Prowl, because the writers thought a Decepticon displaying authority would use the police car form, his form is original to the movie. He mainly elongates his arms to reveal spinning spikes known as the blade wheels in his hands and uses them as close-combat striking weapons. Barricade is one of the main Decepticons in the film, and the very first Transformer to speak English. He first appears hunting down Sam Witwicky to interrogate him about his great-great-grandfather's glasses (that have the location to the Allspark). Sam escapes with Mikaela Banes in Bumblebee's Camaro vehicle-mode, and Barricade chases them. After the chase, Bumblebee transforms into his robot mode, and on arriving, Barricade attacks the Autobot. He releases his partner, Frenzy, to go after Sam and Mikaela, while he battles Bumblebee. Barricade isn't able to kill Bumblebee. However, he survives (as shown by the brief scene showing him as the first Decepticon responding to Starscream's call), and appears later on during the highway chase scene, where Sam recognizes him (as "the same cop"). Barricade disappears after the highway chase scene. He is confirmed to have survived but does not appear in the sequel. Concept art of Barricade Here. He is one of the three Decepticons to have survived the events of the movie.
Bonecrusher - Buffalo H Mine-Protected Vehicle, also original to the movie. His weapons are a claw-like scoop at the end of a large telescopic arm, and guns in his arms. This claw is used in ordnance disposal on Buffalo armored vehicles. His feet are wheels, "skating" as opposed to running. His weapons are a claw-like scoop at the end of a large telescopic arm, and guns in his arms. This claw is used in ordnance disposal on Buffalo armored vehicles. He can also extend his arms to longer degree to grapple his enemies more easily, but he never used this in the film so it stays folded. Bonecrusher is first seen in his Buffalo-vehicle mode, rallying with the other Decepticons to Starscream's call. He is later seen during the highway chase scene with Barricade and Brawl, tossing cars out of his path with his scoop. His clash with the Autobot leader, Optimus Prime ultimately results in his decapitation and death by Optimus. In the sequel a Decepticon sharing Bonecrusher's appearance can be seen. However, he is unnamed in the film and it is unclear if this is intended to be Bonecrusher. Boncrusher in the movie Here. He attacks Optimus on the highway to Mission City and is later killed by him.
Scorponok - Blackouts minion who turn into a Mechanical Scorpion, taken from "Beast Wars: Transformers" (note: Skorponok is not seen transforming between his scorpion and robot form, however the Hasbro toy does have a robot mode. He and his partner Blackout attack the SOCCENT Operations Base in Qatar. Scorponok chases eight Special Forces soldiers across the desert, eventually killing trooper Donnelly, wounding Figueroa, and killing several Qatari soldiers before being wounded in an attack by two A-10 Thunderbolt IIs and an AC-130 Spectre gunship. With the tip of his tail blown off, Scorponok burrows under the desert sands, and is not seen again for the rest of the film. However, the survivors take the damaged tail and bring it aboard a transport plane en route back to the U.S.. While examining the tail, it suddenly goes wild, but Lennox and Epps manage to restrain it. The soldiers also discover through the damage on the tail that while robot armor is impervious to bullets, it can easily be weakened by anti-tank sabot rounds. He is one of the three Decepticons to have survived along with Barricade and Starscream. Concept art of Scorponok Here
Brawl (credited as 'Devastator' on film) - Modified M1 Abrams Battle Tank, his original mode comes from Generation 1. He is heavily-armed, having 8 missile launchers (four on each shoulder), a quad-mounted 37mm cannon on his right forearm, and a small dual blade ('Ripper Blade') and Gatling gun on his left forearm. He has the most weapons of any Transformer seen in this continuity. Brawl is first seen in the film rallying with the other Decepticons to Starscream's call. He is in the highway chase with Barricade, and Bonecrusher. He is later seen during the final battle, announcing his arrival by firing at the Autobots and US soldiers in the streets. Ironhide attacks him with his missiles while performing a Helix twist dodge maneuver, while Jazz leaps onto his frame, pulls on his main cannon causing him to miss,(a stunt that was seen in The Transformers: the movie) forcing Brawl to transform. With his sheer strength, Brawl pulls Jazz off with one hand and throws him against a building. Ironhide distracts Brawl, while Ratchet leaps in and attacks Brawl, cutting off one of his arms. Brawl collapses, seemingly beaten (although the most likely assumption is that he was just stunned, as he was not shot by Ratchet or Captain William Lennox and his team in his most vulnerable partthe chest), minutes later, Megatron lands in a nearby alley. He quickly recovers and rises again when Megatron enters the battle. Brawl continues to mercilessly engage the human forces, until Bumblebee attacks Brawl, still attached to the tow truck driven by Mikaela. Bumblebee shoots him several times in the chest which, combined with shots fired by the human forces, is enough to kill him completely. his dead body was later disposed of. Concept art of Brawl Here.
ALL SPARK MUTATIONS (made with cube's energy and all original to the film)
*Nokia Bot* - A Nokia N93i cell phone formerly owned by Glen Whitmann and transformed into a Transformer by the power of the All Spark. It's a rather violent and hysterical creature, armed with several weapons. In the movie, When asked about the All Spark's energy, Agents Simmons and Banachek took their visitors to a locked room within Sector Seven headquarters. Simmons borrows Glen's Nokia phone and places it inside a protective glass box. Simmons then demonstrated the power of the All Spark by giving life to the Nokia. Transforming into a spidery robot mode, the Nokia robot went crazy and started attempting to escape its glass prison by firing tiny missiles and shooting bullets, as well as slamming itself repeatedly into the glass. When it looked like the creature might break out of the case, Simmons had it blasted with an energy pulse, killing it. Concept art of the Nokia Bot Here.
*Xbox 360* - As a human was walking down the streets of Mission City, carrying his new Xbox 360, a sudden surge from the All Spark granted it life. The new robot's arms and legs burst free of the packaging, and the shocked human threw it away before it could fully escape. It is unknown of what it fate was but in the comic, After the defeat of Megatron and the destruction of the All Spark, US Army Rangers and the Autobots mopped up the remaining creatures mutated by the All Spark's energy. Captain Lennox spotted the Xbox 360 and fired upon it as it was minding its own business, forcing the creature to flee into an abandoned minivan. Ironhide promptly destroyed the van and fished out the creature's remains.
*Cadillac Escalade* - Only its steering wheel transformed into a creepy Transformer with spider-like limbs. It was given life when Sam Witwicky accidentally dropped the All Spark. It seems to like its owner and hugs her face. When Sam accidentally drops the All Spark while fleeing through the streets of Mission City, he bumps into a woman's car. She is angry, and believes he dented her car. This is forgotten as the steering wheel of her car develops spider-like legs, wrenches itself free from the steering column, and clamps itself onto her face, hugging her head while she lets out muffled screams. It is unknown if the whole car was affected by the dropped All Spark or just the steering wheel alone, and whether the woman survived the ominous face-hugging steering wheel. It is unknown what its fate was.
*Dispensor* - One of several robots who transform into Mountain Dew vending machines. This particular one came online during the battle of Mission City. When Sam Witwicky accidentally activated the All Spark during his flight from the Decepticons in Mission City, the artifact's radiation animated an SUV steering wheel, an Xbox 360, and a Mountain Dew soda machine into robots. This Mountain Dew robot, named Dispensor, has an arm-mounted can-cannon. It is unknown of what his fate was. Concept art of Despensor Here.
